I've just installed Debian 11
Is there a default firewall for this version ?
Is it the best option ?

Re: Firewall for Debian 11 desktop
You can see if any service is listening by typing (as root):
in a terminal.
If nothing is listening for external connections, a firewall is pointless.
If you would like to block access to running services, or would like peace of mind in case you inadvertently install an application with a web server, this may be of help: viewtopic.php?f=16&t=143876
Code: Select all
netstat -tulpn

I would recommend you checking out Gufw. They market themselves as "one of the easiest firewalls in the world".

Re: Firewall for Debian 11 desktop
The link shown leads to the Gufw installer for Ubuntu. As gufw is in the Debian repository it would be best to install from Debian. Doing so will ensure that there aren't any surprises such as dependency issues. Always best to stick with Debian.

Re: Firewall for Debian 11 desktop
The closest Debian gets to a default used to be IPtables. This has been replaced by NFtables.
It is recommended to run firewalld . . .
That depends upon you and your needs. Several of the firewall GUIs are simply front ends for IPtables or NFtables.Is it the best option ?
Note that the router/modem you use to access the Internet may have a built in firewall. I set mine to the most secure setting and have never suffered for it.

I shared a link to their website.

Re: Firewall for Debian 11 desktop
Thanks @Hund. I understand. I was just commenting on the link to Ubuntu, concerned that people might download Gufw from that site instead of using the Debian repository.Hund wrote: ↑2021-12-07 11:13I shared a link to their website.
